I claim as my invention:

1. A date recording instrument adapted for use in connection withstorage batteries comprising a dial graduated. and numbered to form onescale designating the days of any month and another scale designatingthe months of any year, a pair of fixedly spaced hands movable over thefirst scale, a single hand movable over the second scale, and mechanismmanually operable to move the pair of hands to indicate two differentdays and to simultaneously move the single hand to indicate the month ofa year.

2. A date recording instrument adapted for use in connection withstorage batteries comprising a dial graduated and numbered to form onescale designating the days of any month and another scale designatingthe months of any year, a pair of fixedly spaced hands movable over thefirst scale, a single hand movable over the second scale, and mechanismmanually operable to move the pair of hands to indicate two differentdays and to simultaneously move the single hand to indicate the month ofa year, said mechanism including a train of gearing and an operatingstem normally urged out of operative engagement with the train ofgearing.

3. A date recording instrument adapted for use in connection withstorage batteries comprising a dial graduated. andnumbered to form onescale designating the days of any month and another scale designatingthe months of any year, a pair of fixedly spaced hands movable over thefirst scale, a single hand movable over the second scale, and

mechanism manually operable to move the pair of hands to indicate twodifferent days and to simultaneously move thesingle hand to indicate themonth of a year, said mechanism including an arbor to which the pair ofhands aresecured, a master gear fixed to the arbor, a pinion fixed tothe arbor, a tubular arbor rotatable on the first arbor and to which thesingle band is secured, a gear fixed to the tubular arbor, a gearmeshing with the pinion, a pinion fixed to the last gear and meshingwith the second gear, and an operating stelnhaving a pinion yieldablyurged out of mesh with the master gear but movable into meshtherewithand rotat able by the stem to actuate the master gear. 4. Adate recording lnstrument adapted for use in connection with storagebatteries comprising a casing, a pair of discs in the casing, threadedstuds having nuts and securing the plates together in spaced parallelrelation one of the disks having on its outer face a dial graduated andnumbered to form one scale designating the days of any month and anotherscale designating the months of any year, a pair of fixedly spaced handsmovable over the first scale, a single hand movable over the secondscale, mechanism manually operable to move the pair of hands to indicatetwo different days and to simultaneously move the single hand toindicate the month of a year, said mechanisi'n comprising an arborjournaled in the disks and to which the pair ofhands are secured, amaster gear fixed to the arbor, a pinion fixed to the arbor, a tubulararbor rotatable on the first arbor and to which the single hand issecured, a gear fixed to the tubular arbor, agear mesh ing with saidpinion, a pinion fixed to the last mentioned gear and meshing with thesecond said gear, an operating-stem having apinion yieldably urged outof mesh with the master gear butanovable into mesh therewith androtatable by the stem to actuate the master gear, and means forrestraining the master gear against accidental rotation comprising acurved fiat spring bearing againstthe periphery of the gear and havingperforated ears receiving certain of the disk securing bolts so as to besecured to the disks.
